Sr. ITOT Network Architect SD-WAN, micro-segmentation

Skills:

Certification in related fields (CCNA CCNP) required. Security and Cisco Certified Internetwork Expert (CCIE) and experience in Extreme network switches is a plus.

10 years of experience in network design and architecture preferably in OT environments.

Experience with industrial protocols (e.g. Modbus DNP3 OPC Ethernet/IP).

Familiarity with IT/OT convergence principles.

Minimum Technical Expertise:

       Knowledge of design configuration installation testing and maintenance of local and wide area computer wired and wireless networks (Cisco Systems preferred).

       Knowledge of computer network characteristics network operating system software and network components

       Troubleshooting skills and the ability to diagnose/resolve network system problems.

       Ability to interpret and apply complex technical manuals and reference materials.

       Ability to assist with developing network security and related procedures; and performing network management activities.

Prefer: Strong understanding of networking concepts including routing switching and firewall configurations.

Prefer: Proficiency in network monitoring and management tools.

Prefer: Knowledge of cybersecurity best practices for OT networks.

Prefer: Experience with industrial control systems (ICS) and SCADA systems.

Architecture & Design

       Design and implement a segmented OT network architecture transitioning from flat Layer 2 networks to SD-WAN-enabled zone-based architectures.

       Define network segmentation strategy (ISA/IEC 62443 zones and conduits model) to isolate critical OT assets and control east-west traffic.

       Engineer ring and/or resilient topologies across substations and core OT sites to ensure deterministic communication and fault tolerance.

       Develop SD-WAN design standards including:

o   Underlay/overlay architecture

o   Path selection policies (latency jitter packet loss)

o   QoS for ICS protocols (e.g. DNP3 Modbus IEC 61850).
